Public bug reported: I've tried this on 15.04 and 15.10 on multiple machines. Supposedly an earlier similar bug for Chrome was fixed for 14.10.
I log in using Guest Login from the lightdm startup screen. I launch chromium-browser or google-chrome. Instead of a window appearing, the terminal says, after some seconds Check failed: NamespaceUtils::DenySetgroups() and then does nothing.
